All I really understood here is "pressure recovery spinner". Sorry, I need translation for rest of it.If it were mine, I would avoid pulling the flow in and then running it nearly straight, then tapering it again. Since we can not avoid some sort of taper to a point or nearly to a point, I fill in the reversed curve there at the aft end of the cowling, and then do the pressure recovery spinner.
